:Be itwknown thatHIQ'WILBUR W; Mnnsn, a

p citizen of the United States of America, and

a" resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements ,in Liners. for Centrifugal v Cream-Separatoraofwhich the following is a I specification.

My. invention relatesrto improvements in liners "for. centrifugal cream separators; and

I .the'obj ect of my inventionis to improve the arating capacitylof that class of-liners chare composed of a'vertical series oLsue perimposedfrusta; by'filling theunoccu'pied and s ace beneath the lowermost frust ry liner t'e bowls bottom with an an adapted to act on the unseparated milk at that location and thus enhanc e'the capacit of the combined liner by increasing {the ba fling surfaces therein; This object I have. accomplished by the means which are 'hereinafter described and claimed, and which are illustrated in the" accompanying drawing, in

which 1- Figure 1 is a central vertical axialfsection:

of a; centrifugal cream separator bowl with my improved combination linertherein, and F g; 2 is an upper lan view of my improved auxiliary device or lining the space con-' tamed between the lowermost frustum and a the bottom of the bowl.

Similar numbers refer 'to similar parts throughout the several views.

The numeral 1 designates a centrifu al. cream separator bowlhaving a cover 2, t e

latter having a central axial opening for the reception :of a hollow clampi "bolt 3 whose upper ende ages the top '0 the fcover by' means of a ct, while -itslower end-is screwed on to a threaded bossinthe-center'of the bottom of-saidbowl; -The. axialinlet hollow of said bolt. is indicatedb the nu metal 4, and the lower endoi the. ltfhasa lateral opening into'the interior-bfi-the bowl; but the lower end of the bolt is shown in ,1 as broken away, the continuation iof same;

downward being indicated The use of a special'form-of bolt or Specification 01 Letters Patent. Application 88 1007. 899,459. 4 :2,

I v able form or-"arranger'nent ofmilk-exit 'such inlet, however, is not by meg since any other suitable type-of bowl with near the axis of the bowl, but also as 5,. andwith a cream-exit','such as 6. v I I have shownin'Fig: I a-well-known t -pe" a *fromthe axial bolt,3, to provide room fol-the am wall as well asa passage just outsidet'i65 of said" cream wall forthe upward fiowofthe searati fullmilk. t will e observed that the frus'ta shown" fill all of .the space in the :bowl above the lowermost of them; but that a considerable un-i tum and thebottom of the bo'wl, which space I have filled with an auxiliary lining device so as to obtain a complete system of lining plates in every part of the hollowinterior of the bowl. If this space was left unoccupied, the whole capacity of the bowl in skimming "would not be in eflective use, when the form of lining device shown above such space is employed. My improved auxiliary device is composed of a plurality of vertic plates 8,.bent;spirally, and having their in.-- ner edges connected to each other by any suitable meansso as to play freely to and from each other when taken from the bowl for the purpose'of Washing them. The parawa the Two ormore small orifices are made near the inner'vertical edge of each plate and a sphtring 9- isinserted in; each horizontal series of "h'ole s,'sojtheplates free1y slide on the rings to and-from each other when the device is rethe bowl.- When thus removed the; plates areieasily separated for cleansin ;'l'It""f;w1 ll'.'bef;qbserved that the plates are eac foi'm edlqn' a s al curve, and this has the ef- Lactate-mm the currents of milk in that a i tlie jbbWF which has heretofore been eft 'v'aci'ntf i v Another result of the peculiar curvaturdnf the plates 8 is to cause a gradual ,,alid"=;prog'ressive diminishin of the inter pacesbetween them from t eir inner edges outward which-not only affords a better time. or the cream as it' separates most nearer-together the bafliing surfaces iof liner, composed ofthe series ot 'hoowQ ,frusta 7 arr ed in vertical superimposedwo filled space is left below the lowermost frusticularmeans employed and shown herein the plates in the outer zone of the device where the nearl skimmed milk does not need so large a c earance in order to void its remaining small percentage of cream globu es. 7

In practice the plates 8 when in operative position in the bowl lie so close together at their outer edges that no retaining device is needed to retain them in their proper place, The milk after moving through this auxiliary device moves upward and moves between the plates 7 in t e usual way, the separated cream moving inward and upward to the cream exit 6, while the skimmed milk seeks the outer zone of the bowl impelled by centrifugal force, and issues thence through the milk exits 5, The combined liner shown completely fills the cavities of the bowl, and

" therefore provides the maximum amount of efficiency in the separating capacity of the bowl. f

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A liner for a centrifugal cream separator, composed, in combination, of a series of superimposed hollow frusta, and aiming de vice adapted to fill the cavity under the owermost frustum, such device being formed of a plurality of vertical plates.

2. A liner for a centrifugal cream separator, composed, in combination, of a series of superimposed hollow frusta, and a lining device ada ted to fill the cavity under the lowermost ustum, such device bein formed of a plurality of vertical plates, suc plates being slidably connected to each other. 3. A liner for a centrifugal cream separator, composed, in combination, of a series of superimposed hollow frusta, and a linin device adapted to fill the cavity under the owermost' 'frustum, such device being formed of a plurality of curved vertical plates.

4. A liner for a centrifugal cream separator, composed, in combination, of a series of superimposed hollow frusta, and a linin de- 1 vice ada ted tofill the cavity within the ow- I ustum, such device being formed ermost of a plurality ofc rved vertical plates connected near their i ner edges.
